Description

Technical Field

[0001] This invention relates to the field of automotive stamping die technology, specifically providing a method, system, and apparatus for determining the maximum movement speed of a filling wedge. Background Technology

[0002] Currently, filling wedges are a common wedge mechanism widely used in automotive stamping dies. To address the slow movement of the filling wedge during the stamping process, the industry commonly employs a large-diameter cylinder to increase thrust. However, this approach has a drawback: the air flow rate provided by the press is fixed per unit time. While increasing the cylinder diameter increases thrust, it significantly reduces the cylinder's own speed, resulting in a decrease in the number of strokes. How to accurately predict the actual number of strokes based on the mechanical parameters of each component of the filling wedge through scientific calculation, and how to rationally set the cylinder diameter and nitrogen spring thrust based on the calculation results, remains a pressing problem for the industry.

[0003] Accordingly, there is a need in the art to solve the above problems by finding a new method for determining the maximum speed of the filling wedge. Summary of the Invention

[0084] Currently, the commonly used technical solution in the industry is to use large-diameter cylinders to increase thrust. This method significantly reduces the cylinder's own movement speed, resulting in a decrease in the number of strokes. To address this, this application proposes a method for determining the maximum movement speed of the filling wedge, thereby achieving fully automated calculation of the wedge mechanism's movement speed. This solves the problem of slow movement speed in the wedge mechanism caused by using large-diameter cylinders to increase thrust in existing technologies, improving the movement speed of the wedge mechanism and thus enhancing stamping production efficiency.

[0085] See appendix Figure 1 , Figure 1 This is a schematic flowchart illustrating the main steps of a method for determining the maximum speed of a filling wedge according to an embodiment of the present invention. Figure 1 As shown, the method for determining the maximum speed of the filling wedge in this embodiment of the invention mainly includes the following steps S101-S104.

[0086] Step S101: Obtain the filling wedge parameter information, which includes at least the filling block parameters, shuttle block parameters, and equipment parameters. In this step, the specific structure of the filling wedge will first be described, as shown in the attached figure. Figure 2As shown, the filling wedge mechanism mainly consists of a filling block 1, a shuttle block 2, a wedge-shaped guide block 3, a nitrogen spring 4, a cylinder 5, and cylinder piping 6. During operation, the shuttle block 2 is driven by the cylinder 5 to move horizontally. During this process, the filling block 1 is driven to the working position by the wedge-shaped guide block 3 on the side of the shuttle block 2. The filling block 1 acts as a movable punch to perform the flanging and shaping of the stamped part. Subsequently, the shuttle block 2 is driven by the cylinder 5 to retract horizontally. The filling block 1, driven by the nitrogen spring 4, retracts to its final position, clearing the negative angle area formed after the stamped part is formed, thus completing the retraction action. Specific parameters of the filling wedge mechanism can be found in the appendix. Figure 3 The filling wedge parameter information obtained in this application includes at least filling block parameters, shuttle block parameters, and equipment parameters. The filling block parameters include filling block weight, filling block motion angle, filling block motion stroke, and nitrogen spring thrust. The shuttle block parameters include shuttle block weight, shuttle block motion stroke, cylinder pipe diameter, cylinder bore, and cylinder pipe length. The equipment parameters include target production cycle time, press air source pressure, and cylinder pipe roughness. In addition, the filling wedge parameter information in this application may also include the coefficient of friction, gravity coefficient, and compressed air density.

[0087] Step S102: Determining the production cycle time and safety factor of the filling wedge based on the filling wedge parameter information includes: First, determining the production cycle time of the filling block, the production cycle time of the shuttle block, and the production cycle time of the cylinder based on the filling block parameters, the shuttle block parameters, the cylinder production cycle time, and the equipment parameters, respectively. Then, determining the safety factor of the filling block, the safety factor of the shuttle block, and the safety factor of the cylinder based on the filling block production cycle time, the shuttle block production cycle time, the cylinder production cycle time, and the equipment parameters, respectively. The specific calculation formulas are as follows:

[0088]

[0089]

[0090]

[0091]

[0092]

[0093]

[0094] In the above formula, SPM1 is the production cycle time of the filler block, SF1 is the safety factor of the filler block, SPM2 is the production cycle time of the shuttle block, SF2 is the safety factor of the shuttle block, SPM3 is the production cycle time of the cylinder, and SF3 is the safety factor of the cylinder. tFor the target production cycle time, μ is the coefficient of friction, g is the gravitational coefficient, ρ is the compressed air density, P is the compressor air source pressure, n is the cylinder pipeline roughness, M1 is the weight of the packing block, θ is the packing block movement angle, S1 is the packing block movement stroke, and F s M1 is the nitrogen spring thrust, M2 is the weight of the shuttle block, S2 is the stroke of the shuttle block, d1 is the cylinder pipe diameter, d2 is the cylinder bore, and L is the cylinder pipe length.

[0095] Step S103: Determine whether the safety factor meets the preset conditions. Specifically, determining whether the safety factor meets the preset conditions includes determining whether the safety factors of the filler block, shuttle block, and cylinder all meet the preset conditions. Furthermore, this can be determined by determining whether the safety factor of the filler block is greater than or equal to a first preset value, whether the safety factor of the shuttle block is greater than or equal to a second preset value, and whether the safety factor of the cylinder is greater than or equal to a third preset value. The first preset value equals the second preset value, and the first preset value is greater than the three preset values. If the safety factors of the filler block, shuttle block, and cylinder all meet the preset conditions, then the safety factor is determined to meet the preset conditions.

[0096] Step S104: Under the premise that the safety factor meets the preset conditions, determine the maximum movement speed of the filling wedge based on the production cycle of the filling wedge. Specifically, under the premise that the safety factor meets the preset conditions, the minimum value among the production cycle of the filling block, the production cycle of the shuttle block, and the production cycle of the cylinder can be used as the maximum movement speed of the filling wedge.

[0097] Based on the above steps S101-S104, the production cycle and safety factor are first calculated based on the acquired input parameters. Then, it is determined whether the safety factor meets the preset conditions. If the safety factor meets the preset conditions, the minimum value of the calculated production cycle is taken as the highest speed that the wedge mechanism can reach. This realizes the fully automated calculation of the wedge mechanism's movement speed, solves the problem of slow movement speed of the wedge mechanism caused by the use of large-diameter cylinders to increase thrust in the existing technology, improves the movement speed of the wedge mechanism, and is conducive to improving stamping production efficiency.

[0098] In one embodiment, the method for determining the maximum movement speed of the filling wedge further includes: adjusting the filling wedge parameter information when the safety factor does not meet the preset conditions, until the safety factor determined based on the adjusted filling wedge parameter information meets the preset conditions. Specifically, this can be: when the shuttle block safety factor does not meet the preset conditions, gradually reducing the nitrogen spring thrust according to a first preset span until the shuttle block safety factor determined based on the adjusted nitrogen spring thrust meets the preset conditions; or when the cylinder safety factor does not meet the preset conditions, gradually reducing the cylinder diameter according to a second preset span until the cylinder safety factor determined based on the adjusted cylinder diameter meets the preset conditions; or when the filling block safety factor does not meet the preset conditions, gradually reducing the nitrogen spring thrust according to a first preset span until the filling block safety factor determined based on the adjusted nitrogen spring thrust meets the preset conditions. When the safety factor meets the preset conditions, the maximum movement speed of the filling wedge can also be determined based on the filling wedge production cycle determined by the adjusted filling wedge parameter information.

[0099] The first preset span in this application can be 100Kg, and the second preset span can be 20mm. (See attached image) Figure 4 As shown, this embodiment will illustrate examples using 2 as the first and second preset values, and examples using 1 as the third preset value. If the shuttle block safety factor does not meet SF2≥2, the nitrogen spring thrust is decreased incrementally in 100kg increments until the shuttle block safety factor determined based on the adjusted nitrogen spring thrust meets SF2≥2. Alternatively, if the cylinder safety factor does not meet SF3≥1, the cylinder diameter is decreased incrementally in 20mm increments until the cylinder safety factor determined based on the adjusted cylinder diameter meets SF3≥1. Alternatively, if the filler block safety factor does not meet SF1≥2, the nitrogen spring thrust is decreased incrementally in 100kg increments until the filler block safety factor determined based on the adjusted nitrogen spring thrust meets SF1≥2.

[0100] In addition, this application can also adjust the nitrogen spring thrust F first if the safety factor of the filling block does not meet SF1≥2. s The judgment is based on the adjusted nitrogen spring thrust F. sIf the safety factor of the filling block meets SF1≥2, then if the safety factor of the filling block meets SF1≥2, determine if the safety factor of the shuttle block determined based on the adjusted nitrogen spring thrust meets SF2≥2. If the safety factor of the shuttle block does not meet SF2≥2, then adjust the cylinder diameter d2 until the safety factor of the shuttle block determined based on the adjusted cylinder diameter meets SF2≥2 and the cylinder safety factor meets SF3≥1. Alternatively, if the cylinder safety factor does not meet SF3≥1, first adjust the cylinder diameter d2, then determine if the cylinder safety factor determined based on the adjusted cylinder diameter d2 meets SF3≥1. If the cylinder safety factor meets SF3≥1, then determine if the safety factor of the shuttle block determined based on the adjusted cylinder diameter d2 meets SF2≥2. If the safety factor of the shuttle block does not meet SF2≥2, then adjust the nitrogen spring thrust F. s Until based on the adjusted nitrogen spring thrust F s The safety factor of the filling block is determined to satisfy SF1≥2 and the safety factor of the shuttle block is satisfied to satisfy SF2≥2.

[0101] In one implementation, after the safety factor determined based on the adjusted filling wedge parameters meets the preset conditions, in addition to determining the maximum movement speed of the filling wedge based on the minimum value among the adjusted filling block production cycle, shuttle block production cycle, and cylinder production cycle, the adjusted nitrogen spring thrust and cylinder bore can also be determined as nitrogen spring thrust and cylinder bore adapted to the maximum movement speed. Furthermore, if the safety factor still does not meet the preset conditions after adjusting the filling wedge parameters, an error message is output, and the minimum value among the calculated filling block production cycle, shuttle block production cycle, and cylinder production cycle is taken as the maximum movement speed of the filling wedge and output.

[0102] If the safety factor does not meet the preset conditions, the parameters of the filling block and the shuttle block are adjusted until the adjusted safety factor meets the preset conditions. The minimum value of the adjusted production cycle is taken as the maximum speed output that the wedge mechanism can achieve, thus realizing the automatic adjustment of the filling block and shuttle block parameters. At the same time, if the adjusted safety factor still does not meet the preset conditions, an error message is output, and the minimum value of the calculated production cycle is taken as the maximum speed output that the wedge mechanism can achieve, thus optimizing the movement speed of the wedge mechanism and improving stamping production efficiency.

[0103] In one specific implementation, as shown in the appendix Figure 5 As shown, the specific parameters obtained for the filler block include the filler block weight M1 = 1860 kg and the filler block movement angle θ = 17. ° The stroke of the filler block S1 = 28mm and the thrust of the nitrogen spring F s=650Kg, shuttle block parameters include shuttle block weight M2=1260Kg, shuttle block stroke S2=90mm, cylinder pipe diameter d1=10mm, cylinder bore d2=200mm and cylinder pipe length L=600mm, equipment parameters include target production cycle time SPM t =15. The compressor air source pressure P = 0.4 MPa and the cylinder pipeline roughness n = 0.012. In addition, the filling wedge parameter information in this application may also include the friction coefficient μ = 0.2, the gravity coefficient g = 9.8, and the compressed air density ρ = 4.6 kg / m³. 3 Based on the method for determining the maximum speed of the filling wedge in this application, the production cycle time of the filling block is calculated to be 29.8, the safety factor of the filling block is 2.0, the production cycle time of the shuttle block is 29.5, the safety factor of the shuttle block is 2.0, the production cycle time of the cylinder is 17.4, and the safety factor of the cylinder is 1.2. Finally, the minimum value of the production cycle time of the filling block, the production cycle time of the shuttle block, and the production cycle time of the cylinder is taken as the theoretical target production cycle time, that is, the theoretical target production cycle time is 17.4.
